There are three things I check when I quickly evaluate new 2-in-1 announcements. Price, performance (CPU, disk, screen) and weight. If the tablet is over 1KG a big buzzer goes off in my head. This 13-inch Satellite Click 2 Pro P30W however has got me inquisitive. 13.3-inches in 1.05KG (2.3 pounds) on an Ultrabook platform makes it quite interesting.

As the Ultrabook design philosophy reaches more of the mainstream laptop market it is becoming more and more difficult to spot new advances in laptop design. NEC makes it easy for us though by launching the sub 800-gram (1.76 pound) LaVie GZ. Energy and space-saving IGZO screen and mainboard means less layers to the laptop cake. There’s a trade-off though.

As I continue my review of the HP Pro X2 410 G1 [first impressions] I’m acutely aware of what’s going on around it this week. The Surface Pro 3 and new products and announcements at Computex have us all thinking about larger-screen tablets and 2-in-1s. One competitor was from HP themselves as Microsoft held up the Pro X2 612 on stage at their keynote. It offers a full HD screen, SSD and Wacom options that aren’t available with the X2 410. It also offers a range of CPUs that start with a Celeron (4th gen Core) and go up to Core i5.

In a press conference at Computex AMD have announced the Kaveri Mobile APU which is targeted at thin and high-performance laptops. It looks like this is a processor that could appear in Ultrabook devices.

Intel are currently presenting on stage at Computex. The press-release reveals what’s about to be demonstrated.

The world’s first 14nm fanless mobile PC reference design from Intel is a 12.5 inch screen that is 7.2mm thin with keyboard detached and weighs 670 grams. The innovative design is based on the first of Intel’s next-generation 14nm Broadwell processors, purpose-built for 2 in 1s and will be in market later this year. Called the Intel® Core™ M processor, it will deliver the most energy efficient Core processor in the company’s history.

So it looks like the days of the U-series processor are over. Perhaps the Y-series too. More importantly it looks like ASUS have used the Intel reference design in their Transformer Book Chi product. Both have a 12.5-inch screen. Both use the ‘next-generation’ Intel core. One is 7.3mm thick, the other is 7.2mm thick. OK, maybe the casing is different!

We’ve never seen an Ultrabook with these specs before. The Asus NX500 Ultrabook was announced yesterday and it proves how far Ultrabook specification can be pushed. The NX500 is targeted squarely at creators and gamers and is one of the most impressive-looking Ultrabooks we’ve ever seen. No, this is not ultra-light, unless you want these specifications in a Windows laptop, and then it is!

Impressive. The Transformer Book Chi 2-in-1 was shown briefly at the Computex show today and although Asus didn’t say it outright, the ‘next generation’ Core processor, slick design and lack of detail in the specifications availability and pricing leads us to conclude that it’s going to be a product built around the 5th-Generation core. It means we’ll probably see this on stage a few more times before we get to see it for sale.

The incredibly thin 7.3mm tablet design is just 14.3mm thick when snapped together with the keyboard. The weight should be just as groundbreaking. The design suggests that it’s fanless too.

The TP300, TP450, TP500 and TP550 Transformer Book Flips have just leaked ahead of an ASUS press conference. These Ultrabook-class 2-in-1s have a Yoga-style 360-degree fold-back screen and will come with 13-inch, 14-inch or 15-inch screens and offer Nvidia discreet GPUs and DVD options.

It’s exactly 12-hours after the launch of the Microsoft Surface Pro 3 as I start to write this article. I’ve spent a number of hours hours researching and making notes on this unique product and have come to one main conclusion. Microsoft has a superbly engineered product in the Surface Pro 3 but it’s too early for mainstream 2-in-1 customers.

Envy, Split, Pavilion. Unlike my fairly clear understanding of the Dell and Lenovo consumer/business product ranges my understanding of HP’s is spotty. Is it just me? When our reader Brad Heath sent me a link to his Pavilion 11 X2 video I was surprised to see a Core i5 version on display and a quick search reveals that it’s new on the market and being offered for just $599 in the USA. Like the Dell Venue 11 Pro series it could offer a perfect balance between laptop and tablet if your primary focus is on productivity. There’s a true SATA SSD, Core i5-4202Y (1.6Ghz + Turbo) and the total weight is under 1.5KG 3/5 pounds. Price: $599 at Microsoft.com which makes it extremely interesting. [Full specs here.]
